Abstract

The present invention provides a method and apparatus for determining an effective channel and feedback information. The method for determining an effective channel comprises: selecting more than one basic column vectors for determining a precoding matrix; calculating products of channel row vectors and the basic column vectors; and determining the effective channel or a Hermitian matrix of the effective channel by using the products. It can be seen from above that with the calculation of products of channel row vectors and more than one basic column vectors determining a precoding matrix and determination of an effective channel or Hermitian matrixes of the effective channel by using the products, the equipment is enabled to lower the amount of calculation and the complexity of calculation, lower the power consumption of the equipment and reduce the circuit size needed in performing corresponding processing in determining an effective channel or Hermitian matrixes of the effective channel and in determining channel feedback information.
